A polygon has the vertices P(-2,6), Q(4,6), R(4,1) and S(-2,1). What is the length of side RS?
inessss [21]
It is 6 units because you find the absolute value of the two different coordinates, in this case it is 4 and -2. Since they belong in different quadrants (one x or y value is positive and the other is negative) you add them. If they are both in the same quadrant, you subtract them.

A supply company manufactures copy machines. The unit cost C (the cost in dollars to make each copy machine) depends on the numb
ArbitrLikvidat [17]

Answer:

  $9327

Step-by-step explanation:

Apparently, the cost function is supposed to be ...

  C(x) = 0.4x^2 -112x +17167

This can be rewritten to vertex form as ...

  C(x) = 0.4(x^2 -280) +17167

  C(x) = 0.4(x -140)^2 +17167 -0.4(19600)

  C(x) = 0.4(x -140)^2 +9327

The vertex of the cost function is ...

  (x, C(x)) = (140, 9327)

The minimum unit cost is $9327.

_____

<em>Comment on the question</em>

You found the number of units that result in minimum cost (140 units), but you have to evaluate C(140) to find the minimum unit cost.

Akimi4 [234]

Answer: T=1/2 Y + -5/2

Step-by-step explanation:

y=2t+5

2t+5 +-5= y +-5

2t=y-5 2t/2=y-5/2

t=1/2y+-5/2

= t=1/2y + -5/2
